Mnemograph

Gives AI coding agents persistent memory across sessions using an event-sourced knowledge graph. Exposes `remember` and `recall` tools over MCP for storing entities, relations, and observations with semantic search. Unlike ephemeral context windows, this versions memory like code with git (branch, commit, revert) and supports tiered retrieval from shallow summaries to deep subgraphs. You get time travel queries, duplicate detection, and graph health checks. Works with Claude Code, Zed, Continue.dev, and other MCP clients. Handles both project-local memory in `.claude/memory` and global cross-project knowledge in your home directory. Useful when you want architectural decisions and debugging gotchas to survive between coding sessions instead of re-explaining context every time.
